cam profile
 

here is a GM cam profile that i was thinking about putting in my 4.3 v6 what do you guys think I have a buddy that used it in an s10 with a set of ported head and it dynoed right at 300hp

This hydraulic roller tappet is a high performance street and marine cam for 4.3L even-fire engines. Use only with roller tappet block on engines without balance shift. The duration at lash point in degrees (intake/exhaust) is 321/316; duration at .050" tappet lift (intake/exhaust) is 224/224; and maximum lift with 1.5:1 rocker ratio (intake/exhaust) is 450/460. Lobe centerline is 112 degrees.

will it work without reversion? I have threw the prop exhaust.
